P Value From Z Score Examples

P-value is used in statistical hypothesis testing, specifically in null hypothesis significance testing. From the below P value from Z Score examples you could see that left-tailed P value is Z < 1 and right-tailed value is Z>1 and two-tailed value is |Z| > 1. You should use the values for Z score between -6 and 6.

Example 1:

Let us consider the problem: What is the P value from Z-Score 0.05?

Solution:

We can calculate the P values using the given formula.

Formula:

To find the P-value from Z-score, you need to use a Z-Score table. Given Z-score: 0.05, Left-tailed P-value: p(Z > z) By using the Positive Z-score table, We get p(Z > 0.05) = 0.5199
Right-tailed P-value: p(Z < z) p(Z < 0.05) = (1 - (Left-tailed value)) p(Z < 0.05) = 1 - 0.5199 = 0.4801
Two-tailed P-value: (|Z| > 1) Two tailed P value = ((Right-tailed P-value) x 2) 0.4801 x 2 = 0.9601
Two-tailed Confidence Level: (|Z| < 1) = 1 - 0.9601 = 0.0399

Therefore, the value of P value from Z score is 0.9601
